IMPROVVED WATCH-WHEEL HOLDER,

The Schedule. referred to in these Letters Patent and making part of the same.

To all whom tt mfr/y concern Beit known that I, AUGUST WILHELM Kmnrorr, of )akland, in the county of Alameda, inl the State of California, have invented a new and ilmprovedWatch- Wheel Holder; and I do hereby 'declare that the fol-Y lowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompzlnylilng drawing, forming part of this specification, in w 1c Figure l represents a longitudinal section of my improved watoh-wheel holder. Figure 2 is a plan or top view o f the same.

Similar letters of reference indicate like parts.

This invention relates to a new implement for hold- 4ing small wheels, such as are used for watches, to allow their ready cleaning and repairing.

Theinvention consists of a tool in which a sexies of spring-jaws is held, vthat will, wheniitted over the spokes ofthe wheel, securely hold the same to' the tool.

A, in the drawing, represents the tubular handle of my nnproved tool, said handle being made of wood or other suitable material, of suitable size, according to the kind of wheels to be handled;

Upon one end of the handle A is fitted a sheet-metal or other tube, B. f l

C is a disk, tted into the tube B. l

From it projects a series of wire rods, D D, said rods fitting through the head a of the tube B, saidv head being perforated to let them pass through.

Each rod D-is bent on the'outside ofthe tube B, to form a hook, b, as shown.

E is a spiral spring, interposed between the' head a and the plate C, tol keep them far apart, and thereby t0 drawthe hooks upon the head a.

F is a rod, fitted through the handle A, and projecting from the lower end of the same," its upper end being somewhat enlarged, as shown;

When this rod is pushed in, it will strike the plate- O, and will move the same against the spring andtoward the head a thereby the rods D will be pushed out.. Then a wheel,.likeA that shown in iig. 2,-can be placed upon the tool, so that its spokes come under the hooks b, and when there the rod F is loose. The spring E will draw the hooks down upon the spokes of thewheel, thereby securely holding the wheel upon the plate a. l

The hooks b areall turned toward the same direction, in the line of a circle, as in iig. 1, so` that the wheel, when the hooks -are raised, can be 'easily tted under them with its spokes, or removed To prevent the spontaneous removal of the wheel, a bolt, G, may be arranged, which ts against a spoke opposite to a hook, l), as shown in iig. 2. v

The handle A need not be tubular. If the tube B is slotted, and a knob projecting from the disk C is fitted through the slot, .the rod F can be dispensed with.

This tool is of great value to watch-makers for holding the wheels duringthe repairing or cleaningioperations. v

vlatch-wheels are made with three, four, and five or more spokes. One tool can only beadapted to one kind of wheels, that shown in fig. 1 having ve hooks for a {ive-spokedv wheel.

A watch-maker provided with three or 'four of these tools, will have enough to handle most all wheels.

Having thus described my invention,

`I claim as new, and desire to secure by Letters Patent The improved tool herein described, its constituent parts being constructed and fitted together'as and for the purpose specified. n

AUGUST WILHELM KIENTOFF.
